95. OULEX ATRIPES, Skuse. 
Wings unspotted ; tarsi uniformly coloured ; thorax dark violet, with 
prothoracic lobes, the pleuree, and a spot in front of the wings 
silvery ; abdominal segments not banded, but with a silvery spot on 
either side ; knees with a minute spot. 
The specimens | refer to this species were received from Calcutta 
and are considerably rubbed. Iam very doubtful as to the identifi- 
cation as the venter is not entirely silvery but more or less banded, - 
In the absence of perfect specimens, however, it is inadvisatle to 
attempt to establish a new species. : 
V 95a. CuLex panaLxctorts (Alcock’s gnat), sp. n. 
Wings unspotted; tarsi unbanded, nearly black; thorax dark 
mouse colour, adorned with lighter lines of the same tint precisely 
as in C. tematus, Meig.; abdomen sooty, dorsally unadorned, but 
with lunate silvery apical bands to the segments as in C. ventralts, 
Walker. 
This species may possibly be C. ventralzs, Walker, but the wings do 
not correspond to my notes on the much mutilated type in the 
British Museum. 
Received from Major Alcock, Superintendent, Indian Museum, 
‘Caicutta. 
97. CuLEX FATIGANS, Wied. 
Wings unspotted; tarsi uniformly brown ; thorax with a median 
and two lateral dark lines, the latter much the most conspicuous ; 
abdominal segments brown, with basal whitish bands ; knees utn- 
spotted. This is a most puzzling species. Mr. Theobald tells me that 
it would be possible to differentiate some 30 species or varieties more 
or less running into each other. In most of these there are no signs 
of thoracic ornament, He differentiates all, however, from C. pipiens, 
L., by the closeness of the posterior transverse to the middle trans- 
verse vein. In any case, during the dry weather, it is out and away the 
commonest of Indian mosquitoes, and some of its forms are to be 
found throughout the year. During the past hot weather it was a 
perfect plague in Lucknow.
